PAPER-ROLL HOLDER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 335,202, dated February2, 1836.

Application filed June '26, 1885.

To all whom, it may concern.-

Be it known that 1, CHARLES C. JOHNSON, a citizen of the United States,residing at Springfield, in the county of XVindsor and State of Vermont,have invented new and use ful Improvements in Paper-Roll Holders andCutters, of which the following is a specification.

This invention relates to improvements in devices for holding rolls ofpaper and cutting pieces of given length from a strip thereof, theobject being to provide an improved apparatus for manipulating acylindrical roll of paper.

In the drawings forming part of this specification, Figure 1 is aperspective view of a device for holding rolls of paper and cutting offpieces from the paper, embodying my in vention, having one arm of theframe. partly broken away. Fig. 2 illustrates detail parts, hereinafterexplained.

In the drawings, A is a suitable base of wood or other material, onwhich the frame B, hereinafter described, is secured, and which providesconvenient means for supporting said frame in proper position in anyconvenient place for use in holding a roll of paper. A metallic frame,B, has two arms, 0 c, thereon projecting horizontally therefrom. In thearm 0 is pivoted the geared segment d, having thereon the projectingcenter pin, 6, extending toward the center between said arms, andadjoining the center pin, e, a pin or projection, 0, parallel with thelatter. The said center pin, 0, and the pin oserve as means for engagingthe segment (Z with the end of a wooden or other cylindrical centerpiece of a roll of paper, as hereinafter described, the end of the pin eentering a central hole in said center piece, and the end of the pin 0entering a suitable hole near the center one,whereby the segment and theroll of paper are caused to have a coinciding rotary motion.

A projecting square center piece on the segment (1, in place of thecenter pin, 6, to enter a square socket in the end of the cylinder f, onwhich the strip of paper is wound, would answer the same end as theprojections e and 0 but .said square socket is less easily formed thantwo round holes, as aforesaid.

The arm a of frame B is provided with a Serial No. 169,810.

(No model.)

removable center pivot, .2, opposite said projection e, the inner orpointed end of which enters a central hole in the end of the aforesaidcylindrical center piece of the roll of paper, and forms a support forone end of the latter. Said removable pivot 2 has a laterally-projeetingwing, .90, thereon, between which and its head is a slot, or, as shown.

The arm 0 has a perforation through it corresponding in form to thetransverse section of the body of the pivot and its wing 00, as shown,and the thickness of arm 0, surround ing said perforation, is equal tothe width of the said slot n in the pivot The abovedescribedconstruction of the pivot z and of the part of arm 0 which receives itprovides means for locking the roll ofpaper to the arms of the frame B,and for conveniently removing a center piece from which the paper hasbeen unwound to place a full roll in the frame, as follows: By passingthe end of the pivot .2 through the perforation in arm 0, and turning itpartly round, the arm is engaged in the slot or in the pivot, preventingthe latter from moving endwise from the roll, and by turning the pivotback to its point of starting it is disengaged from the latter. A knife,10, having preferably a serrated edge, as shown, is attached to suitablearms, on, which have their ends pivotally engaged with the frame B, asshown in Fig. 1,whereby the knife has a vibratory motion between thearms of the frame B. A geared segment, 1 is attached to one of the armsm, which engages with the aforesaid geared segment on the arm a. Arolled strip of paper, h, having said cylindrical or othersuitably-shaped center piece, f, having been placed in the frame B, theoperation of the device is as follows: The knife and the outerends ofthe arms at swing downward against the lower part of the base A bygravitation. The end of the strip of paper on the roll it hangs downwardfrom the outer side of the latter. By seizing and pulling the end of thestrip of paper the roll 71, together with the segment (1, is rotated,and the engagement ofthe latter with the segment 3 on the knife-armcauses the knife to swing up against the under side of the roll, itsedge projecting more or less beyond its periphery. At this point in theoperation the paper is drawn downward against the edge of the knife,whereby a piece is cut off, whereupon the knife drops by gravity to itspoint of starting, and in so doing, through its geared connection withthe roll,causes the latter to rotate in a direction contrary to thatwhich was given to it by pulling the end of the paperstrip, asaforesaid, and, to drop the end of the strip on the roll so that ithangs in a pendent position from the latter ready to be seized, asbefore.

By means of the above-described devices pieces of paper of a givenlength, or substantially so, may be cut from a rolled strip of paper byproportioning the circumference of the roll to the length required.

It will be seen that when the end of the rolled strip of paper is pulledand the roll is rotated the rotary motion of the latter is imparted tothe knife, giving it a vibratory motion, and that when by the separationof the piece of paper from the strip the roll and knife are free thevibratory movement of the knife by gravity is imparted to the roll,causing'the latter to rotate.

What I claim as my invention is 1. In a device for holding a rolledstrip of paper and cutting pieces therefrom, a frame, substantially asdescribed, having arms thereon, a roll of paper hung to rotate betweensaid arms, a knife having a pivotal connection between the latter, andmechanism, snbstantially as described, connecting said arms and knifewith said roll, whereby by pulling the end of said strip and turning theroll the knife is swung against the roll, and by the re for cutting ortearing pieces from a strip of paper, consisting of a frame having twohorizontally-projecting arms thereon, on one of which is pivoted ageared segment having thereon a center to engage with the center pieceof a roll of paper, and having on its second arm a removablelocking-pivot, substantially as described, to support one end of saidroll, combined with a paper cutting knife pivoted to vibrate betweensaid arms, having thereon a geared segment engaging with saidfirst-named segment, substantially as set forth.

4. A roll-holding frame, substantially as described, having armsthereon,between which a roll of paper is pivoted, combined with'apaper-severing knife having a geared connection with said roll, wherebythe rotary motion of the roll imparts a vibratory motion to the knife,and vice versa, substantially as set forth.
